Which Synchronous Modeling command is used to transform faces in a linear or angular direction?

The correct choice is based on the functionality associated with the term "Move Face." This command allows users to manipulate faces of a model in both linear and angular directions effectively.

Using the Move Face command, designers can shift or rotate faces of a solid model to achieve the desired geometry. This is particularly useful in synchronous modeling where quick alterations are necessary without affecting the entire model. The capability to define both the distance moved (linear) and the angle (angular) makes it a versatile tool for design iterations.

In the context of synchronous modeling, this command is especially valuable as it supports a more intuitive modeling approach, enabling designers to interact with geometry directly and make modifications more fluidly. Thus, the emphasis on transforming faces in either linear or angular terms aligns perfectly with the purpose and function of the Move Face command.
